Go to the gunsmith,same meny you upgrade your weapons to MK3 and it's in the underbarrel menuOriginally Posted by klinger112 Go to original post
Upgrading your weapon MK level is not required to use the attachment.
Stenbern was just trying to direct you to the correct screen.
Once you purchase the under-barrel grenade launcher from Maria's shop, you simply need to edit your weapon in the gunsmith, and you'll find it in the under-barrel rail attachments.
Not every weapon can equip the UGL. Most of the ASRs, and the MK14 assault can equip it.
No, what you need to do is go into the gunsmith and hover over the different weapon attachments and then scroll down. The under barrel attachment doesn't actually show to start with so you need to go down to it. This is probably why you are not seeing it there.Originally Posted by klinger112 Go to original post
Just a little advise before you go on with your game,take a look at the different things in your gunsmith,maria's shop,bivuac skill tree etc and learn more about these things in the game and do some researche about the game on the internet will help you alot.Originally Posted by klinger112 Go to original post
